a Timelines of the eruption and lahars with temporal variations in the daily rainfall, daily rate of snowmelt, and snow depth at Tanohara (2190 m a.s.l.: Fig. 1a). The October 2014 lahar was caused by the second rainstorm event after the eruption, whereas the April ROS-induced lahar occurred due to the most intensive water supply which was ~ 400 mm at the end of the snowmelt season. b Hourly rainfall intensity at Tanohara on October 5–6, 2014 (left), and hourly rainfall + snowmelt intensity on April 20–21, 2015 (right). c Daily water input and snow depth at Tanohara from September 27, 2014, to September 25, 2016 (24 months)
